- Root rot - This disease is caused by the fungus Phytophthora sp. and is characterized by yellowing of the leaves, wilting, and eventual death of the plant. To prevent root rot, make sure the soil is well-draining and avoid overwatering. If the plant is already infected, remove and dispose of the affected parts and treat the soil with a fungicide.
- Bacterial wilt - This disease is caused by the bacteria Ralstonia solanacearum and shows up as wilting of the leaves, yellowing, and eventual death of the plant. Once infected, the plant cannot be saved and must be removed from the area, together with the surrounding soil.
Pests
Aside from diseases, various pests can also infest P. parvulus, causing damage to the plant. Here are some of the common pests and how to manage them:
- Aphids - These tiny insects are found on the undersides of young leaves and stems, sucking sap from the plant and secreting a sticky substance called honeydew. To control aphids, spray the plant with insecticidal soap or neem oil.
- Caterpillars - Caterpillars can damage leaves and stems of P. parvulus, leading to defoliation and stunted growth. To manage, handpick and remove the caterpillars, or spray the plant with bacillus thuringiensis (BT).
- Mites - Spider mites can cause stippling and yellowing of leaves, as well as webbing on the leaves and stems. To control, mist the plant regularly to increase humidity, or spray it with insecticidal soap or neem oil.
Overall, it is important to keep a close eye on the health of P. parvulus and take necessary actions to prevent and manage diseases and pests. By doing so, you can ensure that your plant stays healthy and beautiful, providing you with much enjoyment and satisfaction.
